Collection Method: clinical testing

The c.538C>T (p.P180S) alteration is located in exon 9 (coding exon 9) of the COMMD7 gene. This alteration results from a C to T substitution at nucleotide position 538, causing the proline (P) at amino acid position 180 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
